Description
The microfinance industry provides financial services to the world's poor in hopes of moving individuals and families out of poverty. This dissertation document suggests that information and communication technologies (ICTs) are changing the microfinance industry, especially given recent advancements in mobile banking, Internet usage and connectivity, and a decreasing digital divide. These impacts are discussed in three essays. First, ICTs impact intermediation among various players in the microfinance industry. Second, ICTs impact the extent to which microfinance institutions (MFIs) extend their outreach to poorer or more geographically remote borrowers. Finally, ICTs impact the location of decision rights given newly forming peer-to-peer (P2P) social microlending organizations. As the microfinance industry increases its adoption and reliance on ICTs, new and interesting opportunities abound for researchers in the information systems discipline.

Description
Effective professional development has been shown to improve instruction and increase student academic achievement. The Train the Trainer professional development model is often chosen by the state Department of Education for its efficiency and cost effectiveness of delivering training to schools and districts widely distributed throughout the state. This is a study of the Train the Trainer component of an innovative K12 professional development model designed to meet the needs of the state's lowest performing schools that served some of the state's most marginalized students. Pursuing a Vygotzkian social constructivist framework, the model was developed and informed by its stakeholders, providing training that was collaborative, job-embedded, ongoing, and continuously adapted to meet the needs of the School Improvement Grant participants. Schools in the multi-case study were awarded the federal ARRA School Improvement Grant in 2010. Focus questions include: What influence does the Train the Trainer component have on classroom instruction specifically as it relates to formative assessment? and To what extent does the trainer support the implementation of the Train the Trainer professional development at the classroom level? The action research study took place from August 2011 to February 2012 and used a mixed-methods research design.

Description
Biculturalism embodies the degree to which individuals adapt to living within two cultural systems and develop the ability to live effectively across those two cultures. It represents, therefore, a normative developmental task among members of immigrant and ethnic-racial minority groups, and has important implications for psychosocial adjustment. Despite a strong theoretical focus on contextual influences in biculturalism scholarship, the ways in which proximal contexts shape its development are understudied. In my dissertation, I examine the mechanisms via which the family context might influence the development of bicultural competence among a socio-economically diverse sample of 749 U.S. Mexican-origin youths (30% Mexico-born) followed for 7 years (Mage = 10.44 to 17.38 years; Wave 1 to 4).
In study 1, I investigated how parents’ endorsements of values associated with both mainstream and heritage cultures relate to adolescents’ bicultural competence. Longitudinal growth model analyses revealed that parents’ endorsements of mainstream and heritage values simultaneously work to influence adolescents’ bicultural competence. By examining the effect of multiple and often competing familial contextual influences on adolescent bicultural competence development, this work provides insights on intergenerational cultural transmission and advances scholarship on the culturally bounded nature of human development.
In study 2, I offer a substantial extension to decades of family stress model research focused on how family environmental stressors may compromise parenting behaviors and youth development by testing a culturally informed family stress model. My model (a) incorporates family cultural and ecological stressors, (b) focuses on culturally salient parenting practices aimed to teach youth about the heritage culture (i.e., ethnic socialization), and (c) examines bicultural competence as a developmental outcome. Findings suggest that parents’ high exposure to ecological stressors do not compromise parental ethnic socialization or adolescent bicultural competence development. On the other hand, mothers’ exposures to enculturative stressors can disrupt maternal ethnic socialization, and in turn, undermine adolescents’ bicultural competence. By examining the influence of multiple family environmental stressors on culturally salient parenting practices, and their implications for adolescent bicultural competence development, this work provides insights on ethnic-racial minority and immigrant families’ adapting cultures and advances scholarship on the family stress model.

Description
This dissertation consists of two essays with a macroeconomic approach to economic development. These essays explore specific barriers that prevent economic agents from exploiting opportunities across regions or sectors in developing countries, and to what extent the observed allocations are inefficient outcomes or just an efficient response to economic fundamentals and technological constraints.
The first chapter is motivated by the fact that a prominent feature of cities in developing countries is the existence of slums: locations with low housing-quality and informal property rights. This paper focuses on the allocation of land across slums and formal housing, and emphasizes the role of living in central urban areas for the formation of slums. I build a quantitative spatial general equilibrium model to study the aggregate effects of anti-slum policies and use microdata from India for the quantitative implementation. According to my findings, demolishing slums in central urban areas leads to a decrease in welfare, aggregate labor productivity, and urban population. In contrast, decreasing formal housing distortions in India to the U.S. level increases the urban population share by 20% and labor productivity by 2.4%, and reduces the share of the urban population living in slums by 19%.
The second chapter is motivated by the fact that labor productivity gaps between rich and poor countries are much larger for agriculture than for non-agriculture. Using detailed data from Mexican farms, this paper shows that value added per worker is frequently over two times larger in cash crops than in staple crops, yet most farmers choose to produce staples. These findings imply that the agricultural productivity gap is actually a staple productivity gap and understanding production decisions of farmers is crucial to explain why labor productivity is so low in poor countries. This paper develops a general equilibrium framework in which subsistence consumption and interregional trade costs determine the efficient selection of farmers into types of crops. The quantitative results of the model imply that decreasing trade costs in Mexico to the U.S. level reduces the ratio of employment in staple to cash crops by 17% and increases agricultural labor productivity by 14%.

Description
There were two primary goals of this study, the first of which was to replicate previously established curvilinear associations between school affluence and substance use, while assessing potential relations between socioeconomic status (SES) and academic success during the transition to college. The second goal of this study was to establish patterns of perceived parenting factors in order to assess predictive value of such latent profiles with respect to student outcomes relevant to wellbeing and retention in college. Results indicated that substance use was, in fact, associated in a “U-shaped,” curvilinear fashion with high school affluence. Additionally, students grouped into three primary perceived parenting profiles, characterized broadly as “authoritative,” “warm and permissive,” and “uninvolved.” While “optimal” outcomes were associated with students in the authoritative group, these latent profiles lacked predictive value. Supplemental analyses revealed differential associations of various parent factors with males and females, as well as advantaged and disadvantaged youth. Taken together, these results emphasized the importance of parenting during high school in order to promote healthy, safe habits and sufficient self-agency during the transition to college.

Description
This dissertation consists of three essays on modern economic growth and structural transformation, in particular touching on the reallocation of labor across industries, occupations, and employment statuses.
The first chapter investigates the quantitative importance of non-employment in the labor market outcomes for the United States. During the last 50 years, production has shifted from goods to services. In terms of occupations, the routine employment share decreased, giving way to increases in manual and abstract ones. These two patterns are related, and lower non-employment had an important role. A labor allocation model where goods, market services, and home services use different tasks as inputs is used for quantitative exercises. These show that non-employment could significantly slow down polarization and structural transformation, and induce significant displacement within the labor force.
The second chapter, coauthored with Bart Hobijn and Todd Schoellman, looks at the demographic structure of structural transformation. More than half of labor reallocation during structural transformation is due to new cohorts disproportionately entering growing industries. This suggests substantial costs to labor reallocation. A model of overlapping generations with life-cycle career choice under switching costs and structural transformation is studied. Switching costs accelerate structural transformation, since forward-looking workers enter growing industries in anticipation of future wage growth. Most of the impact of switching costs shows on relative wages.
The third chapter establishes that job polarization is a global phenomenon. The analysis of polarization is extended from a group of developed countries to a sample of 119 economies. At all levels of development, employment shares in routine occupations have decreased since the 1980s. This suggests that routine occupations are becoming increasingly obsolete throughout the world, rather than being outsourced to developing countries. A development accounting framework with technical change at the \textit{task} level is proposed. This allows to quantify and extrapolate task-specific productivity levels. Recent technological change is biased against routine occupations and in favor of manual occupations. This implies that in the following decades, world polarization will continue: employment in routine occupations will decrease, and the reallocation will happen mostly from routine to manual occupations, rather than to abstract ones.

Description
Development throughout the course of history has traditionally resulted in the demise of biodiversity. As humans strive to develop their daily livelihoods, it is often at the expense of nearby wildlife and the environment. Conservation non-governmental organizations (NGOs), among other actors in the global agenda, have blossomed in the past century with the realization that there is an immediate need for conservation action. Unlike government agencies, conservation NGOs have an independent, potentially more objective outlook on procedures and policies that would benefit certain regions or certain species the most. They often have national and international government support, in addition to the credibility and influencing power to sway policy decisions and participate in international agendas. The key to their success lies in the ability to balance conservation efforts with socioeconomic development efforts. One cannot occur without the other, but they must work in coordination. This study looks at the example of African Great Apes. Eight ape-focused NGOs and three unique case studies will be examined in order to describe the impact that NGOs have. Most of these NGOs have been able to build the capacity from an initial conservation agenda, to incorporating socioeconomic factors that benefit the development of local communities in addition to the apes and habitat they set out to influence. This being the case, initiatives by conservation NGOs could be the key to a sustainable future in which humans and biodiversity coexist harmoniously.

Description
The parent-child relationship is one of the earliest and most formative experiences for social and emotional development. Synchrony, defined as the rhythmic patterning and quality of mutual affect, engagement, and physiological attunement, has been identified as a critical quality of a healthy mother-infant relationship. Although the salience of the quality of family interaction has been well-established, clinical and developmental research has varied widely in methods for observing and identifying influential aspects of synchrony. In addition, modern dynamic perspectives presume multiple factors converge in a complex system influenced by both nature and nurture, in which individual traits, behavior, and environment are inextricably intertwined within the system of dyadic relational units.
The present study aimed to directly examine and compare synchrony from three distinct approaches: observed microanalytic behavioral sequences, observed global dyadic qualities, and physiological attunement between mothers and infants. The sample consisted of 323 Mexican American mothers and their infants followed from the third trimester of pregnancy through the first year of life. Mothers were interviewed prenatally, observed at a home visit at 12 weeks postpartum, and were finally interviewed for child social-emotional problems at child age 12 months. Specific aspects of synchrony (microanalytical, global, and physiological) were examined separately as well as together to identify comparable and divergent qualities within the construct.
Findings indicated that multiple perspectives on synchrony are best examined together, but as independent qualities to account for varying characteristics captured by divergent systems. Dyadic relationships characterized by higher reciprocity, more time and flexibility in mutual non-negative engagement, and less tendency to enter negative or unengaged states were associated with fewer child social-emotional problems at child age 12 months. Lower infant cortisol was associated with higher levels of externalizing problems, and smaller differences between mother and child cortisol were associated with higher levels of child dysregulation. Results underscore the complex but important nature of synchrony as a salient mechanism underlying the social-emotional growth of children. A mutually engaged, non-negative, and reciprocal environment lays the foundation for the successful social and self-regulatory competence of infants in the first year of life.

Description
Online language learning is becoming increasingly popular with advances in technology that facilitate the acquisition of language in virtual environments (Duensing et al., 2006). Much of the recent literature on online foreign language instruction has focused on the possibilities presented by online technologies but has failed to examine the practical side of how and by whom online language courses are delivered. Several authors have published articles on the skills needed to be a successful online language teacher using empirical approaches (Comas-Quinn, 2011; Ernest et al., 2013; Shelly et al., 2006) and some focus more on the theoretical discussions (Compton, 2009; Hampel & Stickler, 2005). The current study drew on the existing frameworks in the previous literature to operationalize and measure the participants’ online language teaching skills while they taught a class online. These participants were graduate student instructors of Spanish at a large public university (n = 3). Using a case study approach to data analysis (Duff, 2008), and gathering data through a background questionnaire, pre-and post assessments, bi-monthly teaching journals, self- and researcher observations, an exit survey and a semi-structured post-interview, this study investigated how the participants online language teaching skills, proposed by Hampel and Stickler (2005) and Compton (2009), changed over the course of them teaching an online language course and the factors that seemed to influence more or less development in each skill area. Additionally, it compares the main findings from this study with those found in previous literature and offers recommendations of how to promote the development and sustainability of these online language teachers’ skills. This study serves as one of the few empirical studies conducted in the United States that concretely operationalizes and measures through carefully designed instruments the prescribed online language teaching skills in an effort to gain insights into what contributes to their development and how to sustain their continued growth.

Description
This research investigates the dialectical relationships between water and social power. I analyze how the coupled processes of development, water privatization, and climate change have been shaping water struggles in Chile. I focus on how these hydro-struggles are reconfiguring everyday practices of water management at the community scale and the ways in which these dynamics may contribute to more democratic and sustainable modes of water governance at both regional and national scales. Using a historical-geographical and multi-sited ethnographical lens, I investigate how different geographical projects (forestry, irrigated agriculture, and hydropower) were deployed in the Biobio and Santiago regions of Chile during the last 200 hundred years. I analyze how since the 1970s, these hydro-modernization projects have been gradually privatized, which in turn has led to environmental degradation and water dispossession affecting peasants and other rural populations. I frame these transformations using the political-ecological notion of hydrosocial assemblages produced by the different stages of the hydro-modernity—Liberal, Keynesian, Socialist, Neoliberal. I detail how these stages have repeatedly reshaped Chilean hydrosocial processes. I unpack the stages through the analysis of forestry, irrigation and hydropower developments in the central and southern regions of Chile, emphasizing how they have produced both uneven socio-spatial development and growing hydrosocial metabolic rifts, particularly during neoliberal hydro-modernity (1981-2015). Hydrosocial metabolic rifts occur when people have been separated or dispossessed from direct access and control of their traditional water resources. I conclude by arguing that there is a need to overcome the current unsustainable market-led approach to water governance. I propose the notion of a 'commons hydro-modernity', which is based on growing environmental and water social movements that are promoting a socio-spatial project to reassemble Chilean hydrosocial metabolic relations in a more democratic and sustainable way.
